I believe the answer would be implicit wording
I’m what work? You should be more specific.
But in any case, repetition helps focus the audiences attention to what the narrator finds most important. And is an important rhetorical device.
Answer:
The educational setback that occurs when students forget some of the information they learned during the school year is known as summer learning loss (also summer setback or summer slide).
Explanation:
When coming back to school after a long period of holidays, it is common for students to show loss of knowledge and academic skills. That fact can be measured by the use of a standardized test right before the holidays and again when students return to school. The loss varies according to different factors such as age, subject, and even family income. Still, in general, researchers have found that the loss of knowledge is greater in mathematics, and that students in higher grade levels tend to lose more than those of lower grade levels.
My opinion is, they should explain the term they used when writing. This is because the reader needs to under the abbreviation.
